Connecting the lead to the "Ampere" terminal automatically selects the
corresponding function.
When a change of function from the control keypad is
incompatible with the connection of the lead, an audible and
visual alert is triggered (LEADS).
Automatic
power down
The current measurement is made in automatic range mode over the whole
span.
Validate the function by the Standby menu:the device stops automatically
after 30 minutes of operation if during this time there has been no action on
the front panel and if the multimeter remains immobile.
The device is switched back on by the key.
Automatic switching off is disabled in:
Surveillance mode  SURV
Record mode  MEM
Communication mode (isolated USB optical link, Bluetooth)
when the quantity measured (Voltage or Current) on the inputs of the
multimeter exceeds the danger threshold.
Alert signal
An intermittent audible signal is emitted:
* in the "Voltage" setting, when the range is exceeded
(MANUal and AUTO mode - last range)
* in the "Current" setting, when the range is exceeded
(MANUal mode), starting from a measurement of 10 Amperes
* when the connection of the leads is incompatible with the function
selected
* when the danger thresholds are exceeded (if the function is validated)
When the range is exceeded, the audible signal is accompanied by display
of the "O. L" acronym.
When the symbol is activated:
* the voltage on the "Volt" input exceeds 60 VDC or 25 VAC
* the current injected between the "Ampere" terminal and COM exceeds
10A

- Volts x V/A
- Amperes x A/A
to assign the ratio (or transformation ratio) and
the appropriate unit, in order to obtain a direct
reading of the measured current.
Depending on the quantity measured, the
device calculates the function Ax associated
with it.
The programming is in 3 stages:
1. Selection of the quantity measured,
Measurement (V, A)
2. Definition of the ratio A displayed
on the clamp Val1/ Val2 or:
xxxx.XA/xxxx.XV
(default is 1A/1V)
3. Definition of the physical unit to be
displayed (default is A)
The ratio A and the unit can be
programmed for each quantity measured
(V, A).
3. Math
The MATH function (y = Ax + B) enables the
user, measuring any physical quantity in:
- Volts (process 0-10V or high-voltage probe,
for example)
- Amperes 4-20mA current loop or current
clamp, for example)
- Frequency (measurement of flow rates,
speeds of rotation, for example)
- Ohms (resistive position sensor, for
example)
to convert it and assign the appropriate unit, in
order to obtain a direct reading of the original
quantity on the instrument.
Depending on the quantity measured, the
device calculates the MATH function
associated with it.
The programming is in 4 stages:
1. Selection of the quantity measured
(V, A, ,Hz)
2. Definition of the coefficient A of the
function y = Ax + B
3. Definition of the coefficient B of the
function y = Ax + B
4. Definition of the physical unit to be
displayed by the navigator (Upper-case
and lower-case)
The coefficients A and B and the unit
can be programmed for each quantity
measured (V, A,  , Hz).
